design, synthesis and biological evaluation of 4-substituted 5-methyl-furo[2,3-d]pyrimidines is described. The Ullmann coupling of 5-methyl-furo[2,3-d]pyrimidine with aryl iodides was successfully optimized to synthesize these analogs. Compounds 6–10 showed single-digit nanomolar inhibition of EGFR kinase. Compounds 1 and 6–10 inhibited VEGFR-2 kinase better than or equal to sunitinib. Compounds 1 and
描述了4-取代的5-甲基-呋喃并[2,3- d ]嘧啶的设计,合成和生物学评估。5-甲基-呋喃[2,3- d ]嘧啶与芳基碘化物的乌尔曼偶联已成功优化以合成这些类似物。化合物6 - 10表明EGFR的个位数纳摩尔抑制激酶。化合物1和6 - 10抑制VEGFR-2的激酶优于或等于舒尼替尼。化合物1和3 - 10分别的PDGFR-β激酶比舒尼替尼更有效的抑制剂。此外,化合物4 – 11与舒尼替尼相比,在CAM血管生成测定中具有更高的效力。化合物1在小鼠的A498肾异种移植模型中显示了体内功效。多个RTK和微管蛋白的抑制性属性1,4,6和8表明,这些化合物可以是有价值的临床前单剂靶向多种细胞内靶标。
